The page overflowed my screen width when I get into our website homepage few days ago, but it disappeared when I scrolled down about 60% of the page. I think it quite possibly caused by Klaviyo email app. The reason is the issue presented since I installed it and started a signup form that will show up as soon as customers scroll down 60% of the homepage.
It’s possible, but if you’re looking for the forum members here to give some advice (or point you in the direction of a fix) we’d need to see your shop. Any chance that you can post a link to it?
